Friday and Saturday at the 5th annual Engineering Day, students from the Trigg County Primary and Intermediate Schools took a tour of Trigg County High School Teacher Lori Ricks’s engineering class at the vocational school to see what kind of things Ricks is teaching her students.

Everyone in the primary and intermediate schools, except for the second graders, toured on Thursday and for half a day on Friday, and engineering students took them through 13 stations dealing with math, science and technology, Ricks said.

Although the second grade class is usually included in Engineering Day, Ricks said they couldn’t fit them in this year, but they will be able to do tour the facility and build and launch bottle rockets on Friday, May 22.

“I started it … We had engineering days in college, and so when I started here I thought ‘You know, we need an engineering day here,’” Ricks said. “We’ve been doing it for five years now.”

Elementary students worked with Computer Aided Design (CAD) programs on the computers, looked at bridges being built, saw Rube Goldberg devices, and observed a robot, and outside they made silly putty and edible cars, and saw engineering students shoot off water-powered bottle rockets, among other activities, Ricks said.

“We’ve got an electronic marble sorter here that’s sorting it based on light, on how much light passes through the marble,” said Ricks, who went on to say that a few elementary students were duct taped to a board to test the duct tape’s tensile strength.
